STRAIN AND STRESS CALCUALTIONS FOR BLOCKS MANIPULATION IN SHIP PRODUCTION PROCESS

Diplomski rad obuhvaća područje metodologije gradnje broda i strukturne analize broda. Opisani su uzroci i problemi s kojima se susreću brodograditelji tijekom transporta i montaže brodskih sekcija. Napravljen je teorijski uvod u brodograđevni proizvodni proces i metodu konačnih elemenata. Glavni dio je je modeliranje sekcije dvodna i simulacija opterećenja na podkladama i dizanja preko uški. Na kraju su analizirani dobiveni rezultati gdje je objašnjeno koja rješenja su najprihvatljivija.The master thesis covers the field of shipbuilding methodology and structural analysis of the ship. The causes and problems encountered by shipbuilders during the transport and assembly of ship sections are described. A theoretical introduction to the shipbuilding production process and the finite element method was made. The main part is the modeling of the double bottom section and the simulation of the load section when it is standing on the foundations and when it is lifted with the crane hooks. Finally, the obtained results are analyzed and it is explained which solutions are the most acceptable
